電動弁および冷凍サイクルシステム
Document Type and Number:
Japanese Patent JP7220315
Kind Code:
B2
Abstract:
To provide an electric valve capable of properly keeping quietness, and a refrigeration cycle system using the electric valve.SOLUTION: An electric valve converts rotary motion of a rotor stored in an inner periphery of a case into linear motion by a screw feeding mechanism of a male screw member and a female screw member, and moves a valve body stored in a valve main body in a valve center axis direction that is a center axis of the valve body on the basis of the linear motion. A diameter increase in the order of an inner diameter of an end portion on the rotor side of a second valve port, a diameter of a lower end on the second valve port side of an inclined outer peripheral portion, the maximum outer diameter of the valve body, and an outer diameter of a lower end portion on the second valve port side of an extension part.SELECTED DRAWING: Figure 3
